Question

I need to create a recursive update statement that updates from another table so for ex..

    Table1
    (
       IdNumberGeneratedFromAService INT NOT NULL,
       CodeName NVARCHAR(MAX)
    )

    Table2 
    (
       Table2Id Auto_Increment,
       Name NVARCHAR(MAX),
       IdNumberThatComesFromTabl1,
       CodeNameForTable1ToMatch
    )

the issue is CodeNameForTable1ToMatch is not unique so if Table1 has 2 idnumber for the same code and there are two rows in Table2 with the same CodeName I want to update the rows in table2 in sequence so first row gets the first idnumber and second row gets the second id number.

Also want to do it without cursor….

SAMPLE DATA

Table1
idNumber            Code
C145-6678-90        Code1
C145-6678-91        Code1
C145-6678-92        Code1
C145-6678-93        Code1   
C145-6678-94        Code1


Table 2
AutoIncrementIdNumber       Code        IdNumber
1               Code1       {NULL}
2               Code1       {NULL}
3               Code1       {NULL}
4               Code1       {NULL}
5               Code1       {NULL}


C145-6678-90 needs to got 1
C145-6678-91 needs to got 2
C145-6678-92 needs to got 3
C145-6678-93 needs to got 4
C145-6678-94 needs to got 5

in one update statement

Answer 1

This isn’t possible without a cursor.
